    Successful Software Projects and Products: A quantitative study2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Successful or failed software projects have been discussed in literature for many years. Successful software projects are often defined as meeting business objectives, deliver on time and within budget, and meeting requirements. Different factors that contribute to software project success have been identified in the literature. Some of the most common factors that lead to software project success are: user involvement, management support, realistic requirements, and having good estimations. However, there are different opinions about what a successful software project is. Linberg found in a study that managers had a different perception from software practitioners (developers, testers etc.) about what a successful software project is. Since there are different perceptions of what a successful project is among different roles in software development, there may be differences from other perspectives too. This observation relates to the overall research questions in the thesis: Could there be different perceptions about what success factors are for software projects among different countries and customer-supplier relationships? Do people from different countries have different perceptions about what success factors are for software products? This study investigated if there are any differences and similarities between Swedish and Australian companies. In addition, a comparison between bespoke and market driven and bespoke and in-house customer-supplier relationships was made. The result shows that there are differences of which factors that lead to software project success among the two countries as well as between different types of customer-supplier relationships.

    The SICAM-trial: evaluating the effect of spouses' involvement through case management in older patients' fast-track programmes during and after total hip replacement2017In: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 73, no 1, p. 112-126Article in journal (Refereed)
    Abstract [en]

    AimThe aim of this study was to evaluate the effect of spouses' involvement in older patients' care trajectories, using case management as intervention in total hip replacement through fast-track programmes. BackgroundPatients need their spouses to be involved in their fast-track programmes and this involvement is often associated with improvements in patient outcomes. However, the effect of spouses' involvement in older patients' fast-track programmes has not yet been investigated. DesignA two-group quasi-experimental design with pre-test and repeated post-test measures was conducted in an orthopaedic ward of a Danish Regional Hospital from February 2014-June 2015. Spouse-patient dyads were initially recruited for the control group (n=14), receiving usual care; dyads for the intervention group (n=15) were recruited afterwards, receiving case management intervention elements before, during and after admission. MethodsFace-to-face interviews on questionnaires were conducted with spouses and patients at baseline, 2weeks and 3months after discharge, measuring spouses' caregiver satisfaction, difficulties and level of anxiety and patients' functional and nutritional status, pain and level of depression. ResultsThe results showed that there were no differences between the groups with regard to any of the outcome measures. However, statistically significant improvements were found in the patient groups on functional status, pain and depression and in the groups of spouses on caregiver satisfaction. ConclusionThe case management intervention seemed to have an effect in patient and spousal groups; however, this improvement could also have been caused by the effect of fast-track treatment.

    A sense of security: Spouses' experiences of participating in an orthopaedic case management intervention (the SICAM-trial)2017In: International Journal of Orthopaedic and Trauma Nursing, ISSN 1878-1241, E-ISSN 1878-1292, Vol. 24, p. 21-30Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to explore and describe spouses' experiences of participating in a case management intervention during older patients' fast-track programme having total hip replacement as well as which intervention elements they found useful. Data were collected through qualitative interviews with 10 spouses from the intervention group of the SICAM-trial, directed by predetermined codes based on elements of the intervention. Data were analysed by both authors using directed content analysis. The results showed that the spouses were very pleased about being a part of the case management intervention. They enjoyed being active participants even though problems sometimes occurred such as coordination difficulties between the case manager and other healthcare professionals and their feeling of being burdened. The spouses experienced the contact with the case manager as the most meaningful part of their participation and the telephone contact with her as the most useful element of the intervention. The fact that not all spouses participated in all the available intervention elements could be explained by their feeling of being burdened and that they were not fully aware of what the intervention elements were.

    Upplevelsen av att leva med kronisk obstruktiv lungsjukdom: En litteraturstudie2012Student thesis
    Abstract [sv]

    Bakgrund: Kronisk obstruktiv lungsjukdom, KOL, är en obotlig sjukdom som förväntas öka hos befolkningen de kommande åren. Sjukdomen ökar luftmotståndet i lungorna och gör att lungblåsorna förstörs. Det leder till svårigheter med andningen. Rökning är den största riskfaktorn för att insjukna i KOL. Eftersom rökning till stor del orsakar sjukdomen kan känslor som skam och självanklagelse upplevas. KOL hämmar även förmågan till att utföra aktiviteter och påverkar de sociala kontakterna negativt. Syftet: Syftet var att belysa upplevelsen av att leva med kronisk obstruktiv lungsjukdom. Metod: En litteraturstudie med kvalitativ ansats baserad på åtta vetenskapliga artiklar. Resultat: I studien framkom det olika upplevelser som till stor del var negativa. Personer med KOL upplevde andnöd som ett problem eftersom det ledde till panik och ångest och det påverkade den dagliga fysiska aktiviteten negativt. Känslan av att vara beroende av andra upplevdes som frustrerande och var något som var svårt att acceptera.

    Dynamic Creation of Multi-resolution Triangulated Irregular Network2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Context. Triangulated irregular network (TIN) can produce terrain meshes with a reduced triangle count compared to a regular grid. At the same time, TIN meshes are more challenging to optimize in real-time in comparison to other approaches.

    Objectives. This thesis explores efficient generation of view-dependent, adaptive TIN meshes for terrain during runtime with no or minimal preprocessing.

    Methods. Since the workings of the proposed technique is a novel approach, an empirical strategy was employed to present the findings instead of partial comparisons to related techniques.

    Results. To determine the result of the technique, run-time performance is measured and presented to provide incentives for implementation and improvements on the proposed algorithm. Several problem sizes are tested with varying terrain features to determine the effectiveness as a result of the features in the mesh. 

    Conclusions. We conclude that reducing the problem of mesh simplification to that of 2D Delaunay triangulation on sampled points spanning terrains is valid approach for triangulating on-the-fly. Moreover, this approach opens up for further improvements which may soon allow real-time triangulation of TINs.

    Dynamic Creation of Multi-resolution Triangulated Irregular Network2016In: Proceedings of SIGRAD 2016 / [ed] M. Hayashi, 2016Conference paper (Refereed)
    Abstract [en]

    Triangulated irregular network (TIN) can produce terrain meshes with a reduced triangle count compared toregular grid. At the same time, TIN meshes are more challenging to optimize in real-time in comparison to otherapproaches. This paper explores efficient generation of view-dependent, adaptive TIN meshes for terrain duringruntime with no or minimal preprocessing. This is achieved by reducing the problem of mesh simplification to thatof inexpensive 2D Delaunay triangulation and lifting it back to 3D. The approach and its efficiency is validatedwith suitable datasets.

    A study of how risk management can be developed in large industrial R&D projects2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background The interest for risk management has increased a lot during the last years and today it is that important that the customers are demanding the work from the contractors. To make the work easier many tools and aids have been developed but how the real actual work performs within the project teams is something that has not got that much attention in earlier studies.

    Purpose The purpose of the following study is therefore to study how the work regarding risk management performs within the project teams in large industrial R&D organizations to make it possible to develop their work.

    Method For the following study, qualitative methods have been used in terms of interviews and observations. Nine interviews were performed in the study which two were connected to the management department and the rest were performed by project managers. Observations were performed within two different project teams and at one risk review when five different project teams where observed.

    Results The results from the different data collection methods show that communication and knowledge are the keys in the organization. Therefore there is a need for spreading it to make it available for more persons and in this way create an internal education within the organization. Knowledge and experience should be spread both on an individual level but also between the different departments.

    Conclusion If the communication increase the knowledge and experience can be spread out better the organization will receive a better risk result. The organization can also become more competitive since the risk budget can be made more precisely which result in a more competitive price at the market.

    Delimitations The study is restricted so it will focus on the work performed by the project teams in one of the organization’s geographic locations. Regarding the risks, the study will only look at the negative approaches to risk and therefore the so-called opportunities are separated from the study. Likewise are the risks related to health, safety and environmental and also quality since these are handled separately in the organization.

    Improving progress tracking using automated testing techniques2002Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    One of the problems when developing software is the difficulty of knowing how much that is done in a project. This is a basic condition to be able to estimate the remaining efforts with increased accuracy over time. To get accurate progress information it is important that the progress tracking is done in an objective way and also in an as simple way as possible. Our focus in this work has been software projects in general but a case study has also been performed at Ericsson Software Technology AB in Ronneby. We have studied the organization and performed interviews with project managers to find out if this really is a problem and if the process can be improved in some way to ease the task of progress tracking. This case study together with our literature study has resulted in a proposition for a solution. Our approach has been to use automated testing as a way to make progress tracking more objective. The result presented in this thesis is a base for a system that could ease the tracking of progress. In short, the system extracts information from an automated testing process and compares it with estimated figures to be able to automatically generate progress information.

    Situation-dependent spontaneous mobile information service for travelers2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This application is created to provide valid and relevant travel information to travelers on their journey. The application is proposed as a demonstration for seamless communications in the VINNOVA-sponsored project PIITSA (Personal Information Intelligent Transport systems through Seamless communications and Autonomous decisions). The PIITSA-project is a cooperation between Blekinge Institute of Technology (BTH), Saab AB, SP Swedish National Testing and Research Institute and Swedish Road Administration region Stockholm. The project is going on under three years, and the goal is to define communication and decision functions which will make it easier for ITS-applications (Intelligent Transport Systems and Services) that have the need of supplying personalised information. This project presents a solution to the question “How do I get from point A to point B in any case”. All that the user needs is a PDA with the application installed and being able to connect to the service via a mobile network. If the user has specified a route in the application, then the user will receive up-to-date information on how to get to his destination. This information is presented on the user’s PDA. If something happens on the current route, then the user will get an automatic message sent to him presenting the problem and give him a new travel route. Thanks to this the user won’t be stuck in the traffic problem and will probably reach its destination in time.

    A Reverse Engineering Role-Play to Teach Systems Engineering Methods2019In: Education Sciences, ISSN 2227-7102, Vol. 9, no 1, article id 30Article in journal (Refereed)
    Abstract [en]

    Students engaged in systems engineering education typically lack experience and understanding of the multidisciplinary complexity of systems engineering projects. Consequently, students struggle to understand the value, rationale, and usefulness of established systems engineering methods, often perceiving them as banal or trivial. The paper presents a learning activity based on a three-stage reverse engineering role-play developed to increase students’ awareness of the importance of correctly using systems engineering methods. The activity was developed and integrated in the Systems Engineering course given at Blekinge Institute of Technology. Its effectiveness was analyzed through semistructured self-reflection reports along with two editions of the course. The results showed the development of students’ understanding of how to use systems engineering methods. In particular, the students realized the need to deliver detailed and easy-to-read models to the decision makers. This result was in line with the achievement of some of the intended learning outcomes of the course.

    Introducing value driven design in engineering education: teaching the use of value models in preliminary design2019In: International journal of technology and design education, ISSN 0957-7572, E-ISSN 1573-1804Article in journal (Refereed)
    Abstract [en]

    Methods and approaches for teaching engineering disciplines are evolving to adapt to the needs of companies and society. Engineering Design is one of the areas most influenced by such changes and constantly striving to develop more effective and efficient strategies to prepare the soon-to-be engineers to face the challenges of a real working environment. This paper presents an approach used to teach the use of value models for concept trade-off in the preliminary design phase, in line with the industrial challenges highlighted by the literature on Value Driven Design. The approach is based on realistic design sessions assigning to master students a value assessment challenge. The paper describes the rationale of the approach, its set-up, and a validation activity run to compare the performances of the students with those of industrial practitioners. The results of the study show that the students taking part in the design sessions can produce results that do not statistically differ from those of industrial practitioners. Moreover, the students’ self-reflection on the achievement of the intended learning outcomes show a high satisfaction toward the achievement of the educational objectives.

    Value modelling in aerospace sub-system design: linking quantitative and qualitative assessment2015Conference paper (Refereed)
    Abstract [en]

    The paper presents a prototype of a value model where engineering design teams can play with costand value data in a semi-structured way. In particular, the value model serves to facilitatecommunication of multidimensional information during preliminary design analysis and to visualizesuch information in a unique environment. The model first automatically generates, from the output ofa computer-based simulation, a quantitative assessment of manufacturer costs and customer costsaving of a set on different configuration of the same design concept. Second, it couples to the resultsa qualitative assessment of concept risks and product and process commonalities. Third, it allows anassessment of the concept impact on customer “ilities” (maintainability, survivability, scalability,flexibility). The model has been developed in collaboration with an aerospace sub-systemmanufacturer and it ultimately aims to enable the maturation of the knowledge about cost and valueaspects among the design team since the preliminary stages of design.

    Modeling ‘ilities’ in early Product-Service Systems design2019In: Procedia CiRP, Elsevier, 2019, Vol. 83, p. 230-235Conference paper (Refereed)
    Abstract [en]

    Product-Service Systems, like all complex systems, are vulnerable to unpredictable environmental changes that can seriously undermine their ability to continuously deliver value to customers. The long-term consequences of volatile markets, unanticipated technologies, and unpredictable changes in society must be captured, modeled and communicated to decision makers since the earliest stages of the design, so to identify sustainable PSS solutions able to deliver value for years or decades to come. The paper analyses the problem of PSS changeability from the perspective of established medium-large product manufacturers facing the transition toward result-oriented PSS offers. Building on established literature in the systems engineering field, the paper proposes the definition of the changeability criteria, also named ‘ilities’, that are relevant to consider for PSS engineers in the early stages of design. Furthermore, the paper describes a systematic framework for assessing ilities in early PSS design, elaborating on technological enablers for ilities modeling.

    PSS cost engineering: A model-based approach for concept design2018In: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016Article in journal (Refereed)
    Abstract [en]

    Manufacturing companies are increasingly moving toward delivering combinations of products and services to provide higher value to their customers. The development of such Product Service Systems (PSS) escalates in complexity when several products developed by different suppliers need to be integrated into a unique system. For first tier suppliers, it is a great challenge to model and simulate the impact of changing design variables at the micro-level on both hardware properties and governing behaviours of services over the entire life-cycle of the PSS. The paper describes a model-based approach developed to estimate the life cycle cost of a PSS hardware already at a concept design stage.  The proposed approach computes the relative cost efficiency of a set of design variants using as input the data generated by the simulations run in the Computer Aided Engineering (CAE) environment. The approach allows the exploration of the design space of a PSS given by the variation of the geometry of a Computer Aided Design (CAD) model, building on the computation of customised cost modules selected by a generic list of PSS cost dimensions. For each evaluated design case, the model produces as output a unique monetary figure of the cost expected to incur by owning or using the asset throughout the lifetime. The work has been conducted in collaboration with a tier-one aerospace component manufacturer, and the application of the model is exemplified through a case study related to the development of a turbine rear structure (TRS) for commercial jet engines. The approach is most suitable for the development of complex systems in which new products and components are integrated into a shared product platform. The results are discussed in relation to the current literature on PSS cost engineering, highlighting challenges to be addressed to increase cost estimation accuracy and increase uncertainty identification and awareness.

    SUPPORTING EARLY STAGE SET-BASED CONCURRENT ENGINEERING WITH VALUE DRIVEN DESIGN2019In: Proceedings of the Design Society: International Conference on Engineering Design, Cambridge University Press, 2019Conference paper (Refereed)
    Abstract [en]

    Set-Based Concurrent Engineering is commonly adopted to drive the development of complex products and systems. However, its application requires design information about a future product that is often not mature enough in the early design stages, and that it is not encompassing a service and lifecycle- oriented perspective. There is a need for manufacturers to understand, since the early design stages, how customer value is created along the lifecycle of a product from a hardware and service perspective, and how to use such information to screen radically new technologies, trade-off promising design configurations and commit to a design concept. The paper presents an approach for the multidisciplinary value assessment of design concepts in sub-systems design, encompassing the high-level concept screening and the trade-off of different design concepts, and enabling the integration of value models results into a Set-based Concurrent Engineering process. The approach is described through its application in the case study of the development of a subsystem component for a commercial aircraft engine.

    Abstract [en]

    Emerging from a study in the European aerospace industry, this paper identifies a gap in the way value-related information is communicated to designers of hardware in the preliminary stages of Product Service System (PSS) design. To fit this gap a Lifecycle Value Representation Approach, named LiVReA, that uses color-coded 3D CAD models to enable value information to be translated into visual features, is presented. Such approach aims at enhancing designers' awareness of the value contribution of an early design concept on the overall PSS offer by complementing requirements-based information with criteria reflecting the fulfillment of customers and system value. The paper details the development of the approach, its underlying rationale, the results of preliminary validation activities and the potential for industrial application in the light of the currently available PSS representation tools

    Analysing the effects of value drivers and knowledge maturity in preliminary design decision-making.2015In: ICED 15, VOL 10: DESIGN INFORMATION AND KNOWLEDGE MANAGEMENT, Design Society , 2015Conference paper (Refereed)
    Abstract [en]

    The paper presents the results of a three-days experiment to test the use of informationfrom a value assessment model and from a knowledge maturity scale in decisionmakingin preliminary design. A visual analogue scale was used to collect individualinformation from designers through questionnaires. Bivariate statistical analysis wasapplied to study the correlations between both the use of value drivers and knowledgematurity and the designers' awareness of the design problem to be addressed. Resultsshow that value drivers and knowledge maturity information increase the decisionmakers’ awareness of (1) the different perceptions of design team members about theneeds to be satisfied and (2) the technical solution to be developed in the productconcept under consideration.

    Model-based decision support for value and sustainability assessment: Applying machine learning in aerospace product development2018In: DS92: Proceedings of the DESIGN 2018 15th International Design Conference / [ed] Marjanović D., Štorga M., Škec S., Bojčetić N., Pavković N, The Design Society, 2018, Vol. 6, p. 2585-2596Conference paper (Refereed)
    Abstract [en]

    This paper presents a prescriptive approach toward the integration of value and sustainability models in an automated decision support environment enabled by machine learning (ML). The approach allows the concurrent multidimensional analysis of design cases complementing mechanical simulation results with value and sustainability assessment. ML allows to deal with both qualitative and quantitative data and to create surrogate models for quicker design space exploration. The approach has been developed and preliminary implemented in collaboration with a major aerospace sub-system manufacturer.

    Assessing the Value of Sub-System Technologies including Life Cycle Alternatives - an aerospace investigation2011Conference paper (Refereed)
    Abstract [en]

    Emerging from an industrial case study in the aerospace industry, the paper proposes an approach to evaluate sub- system technology concepts from a life cycle perspective. The approach is composed by 5 main phases that aims to drive product designers towards more value-oriented design decisions. It is shown how different life cycle alternatives, such as the selling of a Product-Service-System instead of a traditional product, deeply impact the value of design alternatives. The described approach has been developed in collaboration with industrial partners and represents a potential instrument to enhance value-driven product design.

    Data Mining in Product Service Systems Design: Literature Review and Research Questions2017In: Procedia CIRP / [ed] Tim C. McAloone, Daniela C.A. Pigosso, Niels Henrik Mortensen and Yoshiki Shimomura, Elsevier, 2017, Vol. 64, p. 306-311Conference paper (Refereed)
    Abstract [en]

    The paper presents a literature review about data mining applications in Product/Service-Systems (PSS) design. A systematic literature review, combined with snowballing techniques, has been run to identify relevant contributions in the area. The analysis has focused on the categorization of the contributions according to their impact on the PSS design process and according to their theoretical or empirical nature. A picture of the different research achievements for each stage of the PSS design process have been drawn, identifying the research gaps in respect to the challenges of PSS design. Based on the analysis the paper proposes a set of research questions for each PSS design stage with the intent of facilitating the application of data mining techniques in PSS design, and ultimately push forward the state of the art.

    Mining data to design value: a demonstrator in early design2017In: DS87-7 PROCEEDINGS OF THE 21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 17), VOL 7: DESIGN THEORY AND RESEARCH METHODOLOGY / [ed] Fadel G.,Salustri F.,Kim H.,Skec S.,Van der Loos M.,Maier A.M.,Kokkolaras M.,Oehmen J., The Design Society, 2017, Vol. 7, p. 21-29, article id DS87-7Conference paper (Refereed)
    Abstract [en]

    The paper presents a study run to verify the applicability of data mining algorithms as

    decision support in early design stages of a product development project. The paper

    describes a two-stage scenario providing the rationale for the application of data science in

    engineering design. Furthermore, it describes a demonstrator showing how data can be fed

    back to the early design stages and can be used to populate models to reduce uncertainty in

    decision making. A wheel loader for constructions works is the reference product for the

    demonstration. Data mining is applied on a dataset built on machine performances and

    contextual and environmental data. The demonstrator focuses on the estimation of the fuel

    consumption of alternative design concepts and estimates the performance variations given

    different contextual variable. Finally, a way of visualizing the results of the data analysis in

    relation to the tested and expected performances is presented.

    Abstract [en]

    The aim of the paper is to present an approach for the multidisciplinary evaluation of alternative modular concepts in preliminary design with the intent of enhancing engineers’ capability to simulate alternative scenarios with different design configurations, so to derive decisions about the most valuable design concepts to further develop. The research contribution is novel in the way that it expands the Set-Based-Engineering approach by addressing the “servitization” challenge in two ways: firstly by the use of value models and sustainability models as decision making support, making possible a preliminary assessment of the value contribution and of the sustainability performances of a design concept;secondly, by the use of functional modelling modules and configurable systems elements for platform-based design, to manage the  complex relationships within and between parts of the platform throughout the lifecycle. The paper presents the main features of the approach and introduces an industrial case concerning the development of a module component for an aircraft engine in which the approach is applied for demonstration. The paper finally elaborates on the benefits and implications of the approach in the design process.

    Value-driven product service systems development: Methods and industrial applications2016In: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016, Vol. 15, p. 42-55Article in journal (Refereed)
    Abstract [en]

    In recent times a service-dominant logic is permeating the design of complex systems. However, in spite of their appeal, initiatives such as Product Service Systems (PSS) have not become mainstream, and methods are lacking to support this transition. This paper argues that methodological guidance, as well as tools for decision support, may be found in the research field of Value Driven Design (VDD), which originates in the realm of Systems Engineering. The paper objective is to elaborate on gaps and opportunities for cross-pollination between VDD and PSS. The results of a systematic review of methods and tools for design decision support highlight the opportunity for introducing optimization models derived from VDD in the PSS design process, while the latter can enrich VDD research with a more qualitative value assessment logic. The paper summarizes this integration in a methodological approach, and exemplifies its application in case studies mainly from the aerospace and road construction equipment sector.

    Introducing Sustainability in Value Models to Support Design Decision Making: A Systematic Review2017In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 9, no 6, article id 994Article in journal (Refereed)
    Abstract [en]

    Manufacturing organizations shall recognize sustainability as a business occasion to capitalize on, rather than an undesirable pressing situation. Still, empirical evidence shows that this opportunity is hard to capture and communicate in global strategic decisions, through planning by tactical management, to daily operational activities. This paper systematically reviews the modeling challenges at the crossroad of value and sustainability decisions making, spotlighting methods and tools proposed in literature to link sustainability to customer value creation at strategic, tactical and operational level. While statistical results show that the topic of sustainability and value modeling is trending in literature, findings from content analysis reveal that recent attempts to promote a value-based view in the sustainability discussion remain at a strategic level, with most of the proposed indicators being suited for managerial decision-making. The lack of support at operational level points to the opportunity of cross-pollinating sustainability research with value-centered methodologies originating from the aerospace sector. The Value Driven Design framework is proposed as main hub from which to derive models supporting engineers and technology developers in the identification of win-win-win situations, where sustainable improvements are aligned with business advantages.

    Multi-Criteria Decision Making for Sustainability and Value Assessment in Early PSS Design2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, no 7, p. 1952-1979, article id 1952Article in journal (Refereed)
    Abstract [en]

    Sustainability is increasingly recognized as a key innovation capability in the organization. However, it is not always evident for manufacturers how sustainability targets shall be “mixed and matched” with more traditional objectives—such as quality, time, cost, and performances—when designing and developing solutions. The emergence of “servitization” and product-service systems (PSS) further emphasizes the need for making thoughtful trade-offs between technical aspects, business strategies, and environmental benefits of a design. The objective of this paper is to investigate how multi-criteria decision making (MCDM) models shall be applied to down-select PSS concepts from a value perspective, by considering sustainability as one of the attributes of a design contributing to the overall value of a solution. Emerging from the findings of a multiple case study in the aerospace and construction sector, the paper presents a five-step iterative process to support decision making for sustainable PSS design, which was further applied to design an electrical load carrier. The findings show that the proposed approach creates a “hub” where argumentations related to “value” and “sustainability” of PSS solution concepts can be systematically captured in a way that supports the discussion on the appropriate quantification strategy.

    WORK INTEGRATION SOCIAL ENTERPRISES: A TESTBED FOR CHALLENGE-BASED LEARNING?2019In: Proceedings of the 15th international CDIO Conference, Aarhus university , 2019Conference paper (Refereed)
    Abstract [en]

    Work Integration Social Enterprises (WISE) are a particular enterprise form permeated by a so-called ‘double business idea’. Besides the commercial imperative of providing product and services, WISE offer employment and training opportunities for individuals considered less able to compete in mainstream labour markets. The paper argues that this multiple goal structure makes WISE an ideal testbed for Challenge-Based Learning (CBL). The latter deepens both problem-based learning and CDIO, by featuring open-ended problems that stress an entrepreneurial, value-driven and sustainable approach to problem formulation and decision-making. The aim of this paper is to describe how real-life design projects conducted in collaboration with WISE take CBL a step forward compared with those involving more ‘traditional’ enterprise forms. Evidence is gathered along 4 main lines of thought, which are: 1) iterative problem formulating and designing; 2) entrepreneurial mindset and of value-driven learning; 3) social sustainability-aware designing; and 4) social-constructed learning. The findings indicate that WISE-based design experiences bring forward additional characteristics compared with more ‘traditional’ engineering ones. Students are able to expand the scope and depth of their problem identification and formulation activities, due to the continuous dialogue with a broad range of stakeholders, enthusiasts, and volunteers. They become more aware of the multifaceted meaning of the word ‘value’ in engineering, realizing the existence of competing value systems for the design problem. Eventually their decision-making activities emphasizes the pursuit of different goals and objectives (e.g., technical feasibility, business viability, and sustainable development) in the design process.

    Iterative value models generation in the engineering design process2019In: Design Science, Vol. 5, article id e18Article in journal (Refereed)
    Abstract [en]

    Value models are increasingly discussed today as a means to frontload conceptual design activities in engineering design, with the final goal of reducing cost and rework associated with sub-optimal decisions made from a system perspective. However, there is no shared agreement in the research community about what a value model exactly is, how many types of value models are there, their inputoutput relationships and their usage along the engineering design process timeline. Emerging from five case studies conducted in the aerospace and in the construction equipment industry, this paper describes how to tailor the development of value models in the engineering design process. The initial descriptive study findings are summarized in the form of seven lessons learned that shall be taken into account when designing valuemodels for design decision support. From these lessons, the paper proposes a six-step framework that considers the need to update the nature and definition of value models as far as new information becomes available,moving from initial estimations based on expert judgment to detailed quantitative analysis.

    Abstract [en]

    Nowadays, it is a great challenge to understand what models shall be used to iteratively translate customer desires into terms that are meaningful for engineering design decision-making. This paper proposes a framework illustrating the iterative evolution of model-based enablers for value during conceptual system design. The framework is developed from the analysis of four case studies in the Swedish manufacturing industry. The paper discusses the learning from the cross-case study, and elaborates on how value models may complement existing Systems Engineering practices.

    Nonlinear Quality Function Deployment: an experimental analysis2017In: DS87-4 PROCEEDINGS OF THE 21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 17), VOL 4: DESIGN METHODS AND TOOLS / [ed] Maier, A; Skec, S; Kim, H; Kokkolaras, M; Oehmen, J; Fadel, G; Salustri, F; VanDerLoos, M, The Design Society, 2017, p. 99-108Conference paper (Refereed)
    Abstract [en]

    Quality Function Deployment (QFD) is a common model to frontload engineering design activities with, linking the characteristics of a product vs. the voice of the customer using linear relationships. This approximation is often claimed to be misleading when dealing with the design of complex engineering systems. The paper presents the results of experimental activities aimed at verifying usability and effectiveness of nonlinear functions as extension of the QFD logic. A total of 40 experiments was conducted in a given design episode, involving 139 participants, to analyse the trade-off between the benefit of introducing nonlinearity vs. effort and cost triggered by increased complexity in the modelling. The results show that nonlinear functions, while improving the granularity of the QFD mapping, keeps the method simple enough to work as ‘boundary object’ in cross-functional design teams, irrespectively from the experience of design team members. The experiments also highlight how users’ cognitive attention in the task is dependent from the format by which nonlinear merit functions are presented.

    Using 3D CAD models for value visualization: an approach with SIEMENS NX HD3D Visual Reporting2014In: Computer-Aided Design and Applications, ISSN 1686-4360, Vol. 11, no 3, p. 284-294Article in journal (Refereed)
    Abstract [en]

    Recent literature in Systems Engineering has suggested the use of “value” to drive decision-making activities during preliminary design, in particular when choosing technologies and components for a complex system. However, to correctly evaluate design trade-offs, a visual link has to be established between the results of the value model and a product shape/geometry. This paper proposes the use of color-coded 3D CAD models to support the visualization of value analysis results in a Stage-Gate® process. The approach has been developed and exemplified within a case study related to the design of an aero-engine component, and has been demonstrated using SIEMENS NX HD3D Visual Reporting. The results of verification activities conducted in a laboratory setting show that the use of color-coded 3D CAD models increases the decision makers’ awareness of value-related information in a Stage-Gate process.

    Value Driven Design revisited: emerging modelling concepts and applicatons2019In: Proceedings of the Design Society: International Conference on Engineering Design, 2019, p. 2407-2416Conference paper (Refereed)
    Abstract [en]

    Extended product warranties, leasing, and pay-per-use schemes are few examples of how manufacturing companies are shifting their focus from selling products to offering “solutions”, combining products and services to maximise customer value. The idea of optimising a system towards the best ‘value’ is both "intuitive and sensible", and processes such as Value Driven Design (VDD), have been proposed to supplement traditional engineering design methodologies. Yet, value-driven initiatives struggle to communicate their benefits and to demonstrate how value models can solve actual problems. The aim of this paper is to shed light on the evolution of the VDD toolbox, mapping research clusters, applications and case studies from the perspective of how much (and how well) recent contributions have answered the five top-level questions of the VDD research agenda published in 2012. The results of the systematic literature review reveal the emergence of innovative modelling constructs, methods, and tools that help VDD in taking a leap forward in supporting organizations and teams in achieving the long-sought objective of designing for 'value'.

    Value-oriented concept selection in aero-engine sub-systems design: the EVOKE approach2013Conference paper (Refereed)
    Abstract [en]

    Value Driven Design methodologies extend the Requirements Management and Systems Engineering processes to reduce time and costs needed to identify the right solution direction to be pursued in detailed design. Emerging from the findings of an EU FP7 research project, the paper describes an approach, named EVOKE, that uses value as a basis for preliminary concept selection in the design of system components. EVOKE takes as input a list of value dimensions and drivers communicated by the system integrators, together with information about the high-level engineering characteristics of a candidate design, to enable early stage value analysis to be executed the by sub-system manufacturers. The approach and its technological enablers are described in detail through the use of a case study related to the design of new intermediate compressor case for turbofan engines.

    The development of complex product-service combinations challenges the existing practices for engineering knowledge management. The objective of the paper is to highlight how such practices need to change to meet the engineers’ demand for knowledge when developing “functions” instead of merely hardware. It further proposes Knowledge Enabled Engineering (KEE) as an umbrella term that collects engineering knowledge management methods and tools inspired by the second wave of knowledge management, and that are aimed to meet needs of today’s modern knowledge workers in engineering organizations. The current state of readiness of these approaches is eventually described together with results from verification and validation activities.

    EVOKE: A Value-Driven Concept Selection Method for Early System Design2018In: Journal of Systems Science and Systems Engineering, ISSN 1004-3756, E-ISSN 1861-9576, Vol. 27, no 1, p. 46-77Article in journal (Refereed)
    Abstract [en]

    The development of new technologically advanced products requires the contribution from a range of skills and disciplines, which are often difficult to find within a single company or organization. Requirements establishment practices in Systems Engineering (SE), while ensuring coordination of activities and tasks across the supply network, fall short when it comes to facilitate knowledge sharing and negotiation during early system design. Empirical observations show that when system-level requirements are not available or not mature enough, engineers dealing with the development of long lead-time sub-systems tend to target local optima, rather than opening up the design space. This phenomenon causes design teams to generate solutions that do not embody the best possible configuration for the overall system. The aim of this paper is to show how methodologies for value-driven design may address this issue, facilitating early stage design iterations and the resolution of early stage design trade-offs. The paper describes how such methodologies may help gathering and dispatching relevant knowledge about the ‘design intent’ of a system to the cross-functional engineering teams, so to facilitate a more concurrent process for requirement elicitation in SE. The paper also describes EVOKE (Early Value Oriented design exploration with KnowledgE maturity), a concept selection method that allows benchmarking design options at sub-system level on the base of value-related information communicated by the system integrators. The use of EVOKE is exemplified in an industrial case study related to the design of an aero-engine component. EVOKE’s ability to raise awareness on the value contribution of early stage design concepts in the SE process has been further verified with industrial practitioners in ad-hoc design episodes.

    Designing and implementing a Knowledge Management System (KMS) in a Virtual Enterprise is a labour intensive and risky task. Solution prototypes (Pilots) are usually built to verify system effectiveness prior to final implementation. The paper proposes a methodology to guide this Pilot specifications definition process. These guidelines support engineers and knowledge experts in collaboratively defining functionalities, services, software components and performance indicators of the prototype. The methodology has been conceived and applied within the European project VIVACE, to support the development of a Knowledge Enabled Engineering (KEE) system in the aeronautical domain.

    Social technologies for cross-functional product development: SWOT analysis and implications2012In: Proceedings of the Annual Hawaii International Conference on System Sciences, Los Alamos, CA, USA: IEEE conference proceedings, 2012, Vol. 45, p. 3918-3927Conference paper (Refereed)
    Abstract [en]

    Innovation is triggered by the cross-pollination of fields and disciplines. In product development, this means bringing together people with different expertise to develop breakthrough product and service offers. In spite of their great potential, cross-functional efforts are not yet adequately supported from a knowledge perspective, asking for a more open and bottom-up open approach to knowledge management. The paper aims to investigate how social technologies can enhance collaboration and knowledge sharing in complex, cross-functional and cross-organizational product development projects. It initially highlights the role of weak ties as enablers for more innovative design processes, especially when manufacturing companies move towards developing integrated offers mixing hardware, software and services. Emerging from data collected in two case studies conducted within the European aeronautical industry, it applies the Strength-Weaknesses-Opportunities-Threats (SWOT) framework to highlight how tools such as wikis, blogs, forum and microblogs can shorten and increase the quality of early design decisions. Furthermore it elaborates on how the design team can enhance its perception of the needs to be addressed and leverage its capability to develop solutions for the task at hand.

    Model-driven value assessment: a case from the food packaging industry2018In: Proceeedings of the International DESIGN Conference / [ed] D. Marjanović, M. Štorga, S. Škec, N. Bojčetić, N. Pavković (eds.), The Design Society, 2018, Vol. 1, p. 161-170Conference paper (Refereed)
    Abstract [en]

    Consumer perception of food packaging solutions is driven by early design decisions on paperboard configuration and manufacturing technologies. Simulation Driven Design is common to frontload design activities, but is confined to the engineering field and fails to capture higher-level value aspects. This paper presents an assessment framework connecting customer value dimensions with simulations conducted on the mechanical properties of the packaging material, and discusses how value modelling results can be visualised to support collaborative decision making in cross-functional teams.

    Co-creation in complex supply chains: the benefits of a Value driven Design approach2014In: Product Development in the Socio-sphere: Game Changing Paradigms for 21st Century Breakthrough Product Development and Innovation / [ed] Schaefer, Dirk, Switzerland: Springer International Publishing , 2014Chapter in book (Refereed)
    Abstract [en]

    In the last decade, as the manufacturing companies have reconsidered the overall concept of goods production, their focus shifted from developing ‘products’ to ‘solutions’. In complex supply chains, the combination of products and services that maximize customers’ and stakeholders’ value can be identified only if manufacturers improve their ability to co-create, establishing more interactive relationships with end users, clients and sub-contractors. Methodologies for Value Driven Design (VDD) are emerging as enablers for cross-functional and cross-organizational knowledge sharing, reinforcing early stages design iterations to emphasize the maturation of the requirements across supply chain levels. This chapter highlights the uptake of VDD in a traditionally protective domain, such as the aerospace sector. It describes methods and tools for value assessment, and points toward the most relevant initiatives in this domain. Eventually, it discusses areas of further research to promote the effective use of the VDD methodology while designing complex engineering systems.

    A model-based approach for sustainability and value assessment in the aerospace value chain2015In: Advances in Mechanical Engineering, ISSN 1687-8132, E-ISSN 1687-8140, Vol. 7, no 6, p. 1-19Article in journal (Refereed)
    Abstract [en]

    In the aerospace industry, systems engineering practices have been exercised for years, as a way to turn high-level design objectives into concrete targets on system functionality (e.g. range, noise, and reliability). More difficult is to decompose and clarify sustainability implications in the same way and to compare them against performance-related capabilities already during preliminary design. This article addresses the problem of bringing the important—yet typically high level and complex—sustainability aspects into engineering practices. It proposes a novel integrated model-based method that provides a consistent way of addressing the well-known lack of generic and integrated ways of clarifying both cost and value consequences of sustainability in early phases. It further presents the development and implementation of such approach in two separate case studies conducted in collaboration with a major aero-engine sub-system manufacturer. The first case concerns the assessment of alternative business configurations to maintain scarce materials in closed loops, while the second one concerns the production technology of an aero-engine component. Eventually, this article highlights the learning generated by the development and implementation of these approaches and discusses opportunities for further development of model-based support.

    Value assessment of sustainability hotspots in conceptual design: an aerospace study.2014Conference paper (Refereed)
    Abstract [en]

    Nowadays, when designing structural aero-engine components, the engineering team does not only deal with aerodynamics and structural mechanics criteria. Rather, it needs to make more informed decisions based on the value and sustainability contribution of a design concept. This paper proposes a novel approach that combines qualitative sustainability assessment techniques, which are Environmental Impact Assessment (EIA) and Strategic Sustainability Assessment (SSA), with Net Present Value (NPV) analysis to facilitate early stage decision-making in design. A case study, related to the development of a new high-temperature aero-engine component, illustrates how EIA and SSA identify sustainability hotspots for a new product technology, and how NPV is used to assess alternative solution strategies within the hotspot. Within the studied case, the milling process was identified as a sustainability hotspot, therefore two process options - Electro-Chemical Milling (ECM) and Mechanical Milling (MM) - where benchmarked by calculating their NPV in alternative future scenarios, featuring different market and regulatory assumptions. The approach and its constituting models have been preliminarily verified with designers and process owners in co-located industrial workshops.

    Methods and Tools for Knowledge Sharing in Product Development2011In: Innovation in Product Design: From CAD to Virtual Prototyping / [ed] Bordegoni, Monica; Rizzi, Caterina, New York: Springer , 2011, p. 37-53Chapter in book (Refereed)
    Abstract [en]

    The emerging industrial business partnerships, which feature cross-functional and cross-company development efforts, raise the barrier for the establishment of effective knowledge sharing practices in the larger organization. This chapter aims to highlight the role of knowledge as a key enabler for effective engineering activities in the light of such emerging enterprise collaboration models. Knowledge Enabled Engineering (KEE) is presented as an approach to enhance the extended organization’s capability to establish effective collaboration among its parts, in spite of different organizational structures, technologies or processes. KEE is analysed in its constituent parts, highlighting areas, methods and tools that are particularly interesting for leveraging companies’ knowledge sharing capabilities.

    A methodology for KEE systems target cascading2008In: Proceedings of the 7th International Symposium on Tools and Methods of Competitive Engineering - TMCE 2008 / [ed] I. Horváth and Z. Rusák, Delft University of Technology , 2008, Vol. 2Conference paper (Refereed)
    Abstract [en]

    The main aim of this paper is to present a methodology developed within the European Project VIVACE to guide the design and implementation of a Knowledge Enabled Engineering (KEE) system in a Virtual Enterprise. The proposed methodology tries to overcome some of the limitations which characterise traditional methods for Target Cascading, promoting a more collaborative and iterative approach to derive system specifications (in terms of advanced knowledge functionalities) from initial high-level targets. Social and behavioural aspects of Knowledge Management play a crucial role when many different users, knowledge experts, and process owners are involved in the Knowledge Management System (KMS) development. A well designed methodology is needed, therefore, to enhance communication and information sharing among design teams, to promote requirements merging and to take care both of the technological and behavioural aspects of the implementation. Initial business targets have been step-by-step decomposed into a set of sub-problems (Service Requirements, Knowledge Issues, and Knowledge Challenges) in the form of simple sentences in natural language. Then Quality Function Deployment (QFD) matrixes have been used to identify the set of functionalities to be implemented in the system, addressing the most important knowledge-related problems outlined in the cascading activity.

    The rise of social product development2012In: International Journal of Networking and Virtual Organisations, ISSN 1470-9503, Vol. 11, no 2, p. 188-207Article in journal (Refereed)
    Abstract [en]

    The aim of the paper is to discuss the rising potential of social software to increase the knowledge management capabilities of virtual product development teams. It presents six fundamental transitions, elaborated from the empirical findings, which justify the rise of a more bottom-up, social creation and sharing of engineering knowledge in the virtual organisation. The study suggests that traditional engineering knowledge management approaches alone are not sufficient to support development activities in the virtual organisation, and that such teams display an increasing demand for social, comparatively lightweight and remixable platforms for bottom-up, social creation and sharing of knowledge.

    Requirements for a KEE system supporting PSS development2009Conference paper (Refereed)
    Abstract [en]

    In Product Service Systems development, understanding the customer use of goods is vital, since the product per se is not sold but rather the performance it brings to the purchaser in terms of added value. Moving away from offering just a product or service to become a provider of "integrated solutions" implies inevitable changes in the interaction with the customer as well as in the way knowledge is managed and shared in the cross company environment. The main aim of this paper is, on one hand, to provide examples of how Product-Service Systems raise the demand on such cross-functional knowledge sharing; on the other hand it aims to point out a set of requirements for the successful development of Knowledge Enabled Engineering systems able to support a PSS paradigm in a Virtual Enterprise context.

    Value-driven engineering design: lessons learned from the road construction equipment industry2017In: DS87-1 PROCEEDINGS OF THE 21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 17), VOL 1: RESOURCE SENSITIVE DESIGN, DESIGN RESEARCH APPLICATIONS AND CASE STUDIES / [ed] Maier A.M.,Skec S.,Salustri F.A.,Fadel G.,Kim H.,Kokkolaras M.,Oehmen J.,Van der Loos M., The Design Society, 2017, Vol. 1, p. 319-328, article id DS87-1Conference paper (Refereed)
    Abstract [en]

    Value models, in form of economical optimization functions, are often proposed to frontload engineering design activities. However, literature argues that, when qualitative data and assumptions prevail, a qualitative assessment of the ‘goodness’ of a design is preferable against a numerical (and monetary-based) encoding of preferences. This paper explores how a model-based approach can support deliberation about value in cross-functional design teams. Emerging from case studies in the road compaction equipment industry, the paper analyzes preferences for value modelling support when it comes to iteratively translate customer desires into terms meaningful for engineering design decision-making. It further prescribes a framework for value-driven engineering design that considers the need to update the value model definition as far as new information become available in the process, moving from qualitative to quantitative. The findings highlight the role the proposed chain of value models plays in terms of providing a shared reference to stimulate value discussions across functions and organizational roles, which is something that does not naturally happen in the organization today.
